We attempt to propose the first orthogonal-state-based protocols of measurement-device-independent quantum secure direct communication and quantum dialogue employing single basis, i.e., Bell basis as decoy qubits for eavesdropping detection. Orthogonal-state-based protocols are inherently distinct from conventional conjugate-coding protocols, offering unconditional security derived from the duality and monogamy of entanglement. Noise imposes a major challenge to the efficient implement

The National Array of Neutron Detectors (NAND) at IUAC is one of the big detector arrays used in experiments to study nuclear fission through the measurement of the neutrons emitted during the process. The array is installed at IUAC heavy ion accelerator facility. NAND consists of 100 liquid scintillators mounted on a semi-spherical geometry covering a total of 3.3\(\%\) of 4\(\pi\) solid angle. The 175-cm-long flight path provides good energy resolution of the emitted neutrons, enabli

The originally private notes below were posted in March 2022, for the purpose to make them available to interested parties in a public-domain way, and not intended to be submitted for publications [1]. As such, it was the first publication exploring interplay between altermagnetism and superconductivity. The editors of this Special Issue suggested to use it as a brief introduction; this make sense from the history point of view, so it is being published here in an unaltered form, and no attempt

Non-equilibrium dynamics have become a central research focus, exemplified by the counterintuitive Mpemba effect where initially hotter systems can cool faster than colder ones. Studied extensively in both classical and quantum regimes, this phenomenon reveals diverse and complex behaviors across different systems. This review provides a concise overview of the quantum Mpemba effect (QME), specifically emphasizing its connection to symmetry breaking and restoration in closed quantum ma

The study of strongly correlated electron systems remains a fundamental challenge in condensed matter physics, particularly in two-dimensional (2D) systems hosting various exotic phases of matter including quantum spin liquids, unconventional superconductivity, and topological orders. Although Density Matrix Renormalization Group (DMRG) has established itself as a pillar for simulating one-dimensional quantum systems, its application to 2D systems has long been hindered by the notoriou

As two-dimensional (2D) semiconductor devices demand ever higher performance and tunable photo-energy responses, the ability to probe and control exciton-trion interconversion has attracted much attention. However, conventional optical studies predominantly rely on far-field schemes, which suffer from inherent limitations, such as low spatial resolution and weak photoluminescence signals, restricting practical applications. To address these challenges, plasmonic structures have been em
